Force Redraw Switch
This switch defines if an open of a file is treated as the Restart or as the Redraw operation. Here under ‘open a file’ operation these actions are meant:
The default is restart and the change of this behaviour is not saved for a later use to avoid confusion of users from a possible strange SPLOT behaviour.
By checking this switch the redraw mode will be used. This can be useful namely for observation of detailed (zoomed, trimmed etc.) differences between two or more files, for monitoring of detailed changes in one file (can be done automatically via File Watching) etc. However please note that some view attributes (zoom, trim, rotation) can be preserved only when the used paper size is not dynamically changed between redraws (i.e. there is no change in PS instruction between redraws).
